General Description

The keyless entry system is a supplementary vehicle entry device. Radio frequency interference or discharged batteries may disable the system.

Keyless entry allows you to operate the following components:
^ The door locks
^ The rear compartment lid release
^ The illuminated entry lamps
^ The panic alarm (instant alarm)

The keyless entry system has the following main components:
^ The transmitters
^ The Body Control Module (BCM)
^ The Remote Door Lock Receiver (RCDLR) which was added midyear to certain vehicles.

When you press a button on a transmitter, on vehicles with ONLY a BCM, the BCM receives and interprets the signal and activates the requested function. On vehicles with a RCDLR, the transmitter sends a signal to the RCDLR. The RCDLR receives the signal and sends a serial data message requesting the appropriate function from the BCM..
